Abstract
The invention discloses a pin shaft dismounting tool. The pin shaft dismounting tool comprises a screw adjusting device, a pull block fixing device and a hydraulic device. The hydraulic device comprises a hydraulic cylinder, a hollow piston, a hydraulic joint, a manual hydraulic pump and a hydraulic hose. External force is applied to a pull block through the hydraulic device, and the upper end, which is in threaded connection with the pull block, of a screw is driven to move upwards, so that a pin shaft which is threaded connection with the lower end of the screw is pulled out. Due to the fact that a rough-rolled guiding support arm and a medium-rolled guiding support arm cannot deform when the pin shaft is dismounted through the pin shaft dismounting tool of the structure, the pin shaft is not liable to be damaged and can be easily and rapidly dismounted.
Description
One, technical field: the present invention relates to a kind of pin shaft disassembling tool, particularly relate to a kind of be applicable to thick, roll the specific purpose tool that guide and guard support arm shaft is dismantled.
Two, background technology: at present, guide and guards works extremely severe when, irregular stress, by the frictional influence under high temperature and hot change impacts, high temperature, cause thick, in roll the support arm shaft deformation of guide and guard serious, occur that corrosion is not easily changed.Dismounting is thick, in what roll that guide and guard support arm shaft adopts is general tool dismounting, it is simply that coordinate with screw and sleeve, adopt Weight type drawbench to carry out dismounting hinge pin.This dismounting mode is it cannot be guaranteed that each support arm shaft can be extracted smoothly, for the in the case of of can not extracting, it is necessary to the gap location being connected from guide and guard housing with support arm with burning torch, carries out flame cutting.
Three, summary of the invention: the object of the invention is exactly: long for the dismounting guide and guard support arm shaft take-down time at present, labor intensity greatly and is not drawn out easily；Use burning torch to process and not only scrapped bearing pin, also guide body is caused damage, cause guide and guard support arm and support arm axis hole temperature distortion, affect the defect of the assembly precision of guide and guard, it is provided that a kind of be applicable to slightly, roll the specific purpose tool that guide and guard support arm shaft is dismantled；
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:
There is provided a kind of suitable in thick, roll the specific purpose tool of guide and guard support arm shaft dismounting, it includes: screw rod adjusting apparatus (1), pulling block fix device (2), hydraulic means (3) forms.Material all adopts 65# Fine Steel Casting iron.
Hydraulic means (3) is cylindrical structural, mainly it is made up of hydraulic cylinder (4), hollow piston (5), hydraulic joint (6), hydraulic hand-pump and hydraulic hose, adopt box-structure, upper end is connected with the fixing device of pulling block, and lower part is connected with guide and guard support arm.
Screw rod adjusting apparatus (1) diameter is M16mm screw element, upper end screw rod adjusting apparatus is connected with the fixing device of pulling block, the fixing device of pulling block can being carried out height adjustment and fixing, lower end screw rod is mainly fixed with guide and guard bearing pin one end, upper end screw rod be adjusted.
It is 30mm that pulling block fixes device (2) for rectangular structure thickness, mainly fixed hydraulic device and screw rod, and female thread connects screw rod and can adjust up and down.
Four, accompanying drawing illustrates:
Below according to the drawings and the specific embodiments, the present invention is described in further detail.
Fig. 1 is the assembling schematic diagram of the present invention；
Fig. 2 is the side view of parts (1)；
Fig. 3 is the side view of parts (2)；
Fig. 4 is the side view of parts (3)；
Five, detailed description of the invention:
Pin shaft disassembling tool as shown in Figure 1 includes: screw rod adjusting apparatus (1), pulling block fix device (2), hydraulic means (3) composition.Wherein hydraulic means (3) is cylindrical structural, by hydraulic cylinder (4), hollow piston (5), hydraulic joint (6) and hydraulic hand-pump and hydraulic hose composition.
As shown in Figure 1: first by hydraulic means (3), be placed into thick, in roll the top in direction corresponding to guide and guard support arm shaft, by screw rod adjusting apparatus (1) the hollow hydraulic cylinder of traverse (4), screw device (1) lower end and support arm shaft threaded engagement also fasten, and screw device (1) upper end and fixing device (2) threaded engagement of pulling block are also fastened to just and the position of the upper surface of hydraulic cylinder (4)；Hydraulic hand-pump, hydraulic hose are connected with hydraulic joint (6), operation hydraulic hand-pump make pulling block fix device (2) drive screw rod adjusting apparatus (1) move upward, separate so that bearing pin props up arm aperture with guide and guard, extracting support arm shaft, action closes hydraulic means (3) after completing.
As in figure 2 it is shown, screw rod adjusting apparatus (1) material is 65 carbon constructional quality steels, length is 300mm, the external screw thread of screw rod upper and lower end 100mm place processing M16, screw rod upper end device (2) threaded engagement fixing with pulling block；Screw rod lower end and support arm shaft threaded engagement.
As shown in Figure 3, it is 65 carbon constructional quality steels that pulling block fixes device (2) material, length is 120mm, width is 30mm, the female thread of the center processing M16 of pulling block length direction, pulling block fix the cooperation of device (2) and screw rod threaded upper ends and is fastened to the position of upper surface of lucky and hydraulic cylinder (4)；
As shown in Figure 4, hydraulic means (3) is by hydraulic cylinder (4), hollow piston (5), hydraulic joint (6) and hydraulic hand-pump and hydraulic hose composition.Hydraulic cylinder cylinder diameter is 80mm, the maximum pressure allowed is 50 tons, stroke is more than 40mm, be placed on thick, in roll the top in direction corresponding to guide and guard support arm shaft, the fixing device (2) of pulling block is applied external force, thus driving the screw rod threadeded with the fixing device (2) of pulling block to move upward, extract support arm shaft bearing pin.
